MAKING of PLASTIC BAG
As we are aware of the recent decision taken by Indian government regarding the ban on usage of plastic bag all over the country, which can make us curious about,"What exactly made our government take such a concrete step"?
So for that we have come with some not so known facts regarding Plastic bags manufacturing.
and It's harmful effects.
Manufacturing of Plastic bags.
1. Plastic bags, we use are made up of granules of linear polyethene resin that would be melted then mixed with other granules to make a homogenous material.
2. The polyethene, which we use for plastic bags are derived from refined oil and natural gas from underground through the drilling process.
3. The raw oil is sent through pipes to refinery. Petroleum is separated at these sites into various different - different densities so that the appropriate oil needed for plastic can be extracted. (The densities we get depends upon the amount of temperature and pressure we apply)
4. Plastic film is produced by a process called Blow extrusion process, in this process, raw material like HDPE and LDPE are again pressurised and heated to form a uniform molten liquid, thereafter, the air is blown from below to produce a long thin balloon of plastic film that passes through a vertical corridor.
5. The plastic bags are them rolled on the roller for further processes like printing, cutting and pasting.
Harmful Effect of Plastic Bags
1. Plastic bags kill about 100,000 animals(whales, dolphins, turtles, penguins) annually.
2. Plastic bags are Non-biodegradable, it takes about 1500 years to completely decompose.
3. Harmful chemicals are released during the manufacturing of plastics.
4. Plastic can increase various types of cancers.
